Application filed February 6, 192 8. 'S eria1 No.'252,307.

This invention relates to' spring air. guns of that type which simulatethe appearance 1 of the so-called pump gun and in which the spring is.compressed .by the sliding of the i pump handle on the barrel.

It'is one of the primary objects of the present invention to provide agun of the foregoing construction capable of producing a reportsimulating ithat of a rifle without discharging the projectile from thebarrel.

In the type of pop guns heretofore used considerable inconvenience hasbeen experienced in the necessity of breaking the gun adjacent the stockthereof for compressing the spring to place the gun in cocked position.-Moreover in this later type of construction it has been usuallynecessary for the operatorto place the projectile within the barrel sothat upon firing the gun the projectile will be discharged from thebarrel to produce the desired report. 7 rangement is satisfactoryforproducing the desired results it has been found objectionablenotjonlydue to the time required to place the gun in firing conditionbut also due to the number of parts necessary for the efficientoperationrof the gun. 1

The present invention contemplates eliminating the foregoingdisadvantages by pro- ,viding a pop gun having the pump type operatingmeans for compressing the spring and having means depending upon theoperation of the pump for automatically insertlng the.

projectile in the air chamber.

Many of the advantages and muchof the 'commercial'value andacceptability of the invention is attributed to the novel constructionof the gun, thesefadvanta'ges being obtained.

. particularly because of the simplicity of the construction andtheminimum number of parts employed. This enables the entireconstruction to be-economically and quickly manufactured and easilyassembled andrenders the same strong and durable. The inventiontherefore depends for some of its advantages upon the specific detailsof construction which will be made more apparent as this descriptionproceeds especially when considered in connection with the accompanying.

Figure 2 is a sectional view ofthe gun showingthe spring in releasedposition.

Figure 5 is a sectional line 5..5 of,Fi ure p Referring now moreparticularly to the drawing wherein like reference characters inviewtaken on the dicatelike parts, it will be noted that in F igure 1 thereis illustrated an air gun 10 havinga barrel 11 anda stock 12. Sleevedwithin Figure 4 is a sectional view taken on the i the barrel; 11 andsecured thereto adjacent the rear end thereo'fis a tubular member 13normally sealed-at the forward end thereof by means of a suitableprojectile 13 whichcooperates with the tubular member to form an aircompression chamber. Slidably arranged Within this chamberfor'compressing the air plunger, is of sufficient length to engagebehind the projection 19 of the trigger 20, in the cocked position ofthe gun as shown in Figure 3. "Fornor'mally urging the-plunger to theposition illustrated in Figure 2 I provide a coil spring 21surroundingthe shank portion 15-of the plunger'and engageableat theforwardfend with theplunger and attherear end with the trigger housing.

In order to cook the gun, or-in other words, 1

move the plunger rearwardly to the extent that theho oked portion 17engages behind the projection 19 of the trigger '20 andthereby compressthe spring 21, I provide the mechanism indicated generally by thereference nu-.

pump handle 28 having the circumferentially extendinggroove 24' therein.Arranged within this groove 1s an annular member 25 havmoral 9,2; Thismechanism comprises the a lateral projection 26 terminating in anupwardly extending portion 27. As shown this latter portion pro ectsthrough an elongated slot 28 formed in the bottom of the bartion of theannular member 25.

rcl'11 adjacent the tubular air chamber 13 and is formed with a diameterslightly smaller than the interior diameter of the barrel 11. With thisjarrangement of parts it will be noted that the portion 27 performsthree distinct-functions in the operation of the gun,

first, slidablysupport. the forward end of the pump handle upon thebarrel; second,

forms ahument for the projectile upon firing the gun to retain theprojectile within the r barrel, and third, operates upon moving the p nphandle rearwardly topositively engage the projectile and move the sameinto sealing engagement with the forward end of the compression chamber.Thus a triple function is s.-

a eributed to this portion of the apparatus.

Forconnecting the pump handle '23 with the plui'iger I provide a rod 29having the substantially flat portion 30 at theforward end thereofembedded within the handle 23 and cutaway asat 31 for receiving a por-The rear end of the rod 29 is preferably'offset as indicated at 32 andisadapted to project into the trigger housing 16 and engage the hookedportion 17 of the plunger 1 1. In order to normally maintain the pumphandle and rod 29 in their extremeforward or inoperative positions thecoil spring 33 is provided. As shown, this spring is secured at theforward end to the barrel and at the rear end to the extension 29carried by the pump handle 23, the arrangement being that upon movingthe handle 23 rearwardly to compress the sprin 21 the spring 33 isplaced under tension so that after the gun has been cocked the handle 23upon being released by the operator will instantation 32 of the latterengages the hooked portion 1'? depending from the shank 16 of theplunger and moves the latter rearwardly to compress the spring 21 andengage the hooked. portion aforesaid behind the projection 19 on thetrigger 20. The latter is normally maintained in the path of the hookedportion by means of the spring 34: engageable at one end in the recess35 and at the opposite end with the forward end of the stock 12. Asheretofore pointed out during the compressing of the spring 21 theextension 27 carried bv the handle 23 will operate to move theprojectile 13 into sealing engagement with tne air compression chamber.With the parts in this position and it is desired to discharge the gunthe trigger is moved rearwardly about 7 extent that the projectile willbe forced from the end of the chamber, permittingv the air to escapeinto; the barrelill; and. through the elongated slot 28 thereinproducing the de sired report. Upon discharging the projectile from theend of the air compression chamber the former will'stri-ke the extension27 and accordingly be prevented, from escaping to thee-xteriorofthebarrel. If desired, a suitable opening 36 may be provided on the top ofthefbarrel 11 adjacentthe chamber 13 so that the operator may determinewhether or not the projectile is in proper sealing engagement with thechamber.

' Thus from the foregoing it will be apparent that the herein describedarrangement offers the possibility of using a novel type of pumpactuating mechanism for simultaneously compressing the spring of a popgun and loading the same in which the usual foldinglinks and theiraccompanying inefii cienjciesare dispensed Withan'cl one in which thefreque cy of operation is greatly increased owing to the comparativelyshort tii erequired to place the gun in firing con- Clc lOll,

Another novel feature of construction of this invention, whichcontributes materially tothe'reduction in cost of manufacture and.tot-he general appearance of the, gun, is the provision of a'triggermember formed from a single sheet of metal and having a portionsimulating the usual trigger guard construction.
